Many versions of pumpkin bars are crowned with a cream cheese topping, but this version features a buttery and chewy oat-crumble—both as the bottom and top crust. The pumpkin filling in these delicious pumpkin squares is spiced with cinnamon, ginger, and other typical "pumpkin pie" spices, making for a quintessential fall treat.

These pumpkin bars with oat crumble crust can be enjoyed almost any time of day, whether an indulgent breakfast, late morning snack, afternoon pick-me-up, or tasty dessert. They're also perfect for packing in the lunch box. Feel free to use store-bought pumpkin spice or make your own from scratch.

Make Your Own Pumpkin Pie Spice

To make the spice mix from scratch, combine 1 1/2 teaspoons ground cinnamon, 3/4 teaspoon ground ginger, 1/4 teaspoon ground nutmeg, and 1/4 teaspoon ground allspice.

Pumpkin Puree vs. Pumpkin Pie Filling

Although both of these canned products can sit side-by-side on the grocery store shelf, pumpkin puree and pie filling are two different things. Pumpkin puree, which can also be labeled "100 percent pure pumpkin," "solid pack pumpkin," or simply "pumpkin," is simply cooked and mashed squash without any sweeteners or seasonings added. Pumpkin pie filling, on the other hand, does include ingredients to add sweetness and flavor, making it a convenience when baking pumpkin pie or other pumpkin desserts. Although you can use pumpkin puree in place of pie filling (and add the necessary spices and sweeteners), it is trickier to substitute the pie filling for the puree as it's more difficult to eliminate flavorings and maintain the integrity of the recipe.
